a corporation of New Jersey Application November 26, 1942, Serial No. 467,003 3 Claims. (01. 242-25) This invention relates to machines for coiling or reeling wire and the like.

The main object of the invention is to provide a simple mechanism by means of which the initial and, therefore, usually unprocessed, damaged or unusable end of a long length of wire to be coiled or reeled may be segregated during the coiling or reeling from the remainder during coiling orreeling so that it may be readily disposed of.

The other and more detailed objects of the invention will be apparent from the following description of one embodiment thereof as illustrated in the attached drawings.

This invention resides substantially in the combination, construction, arrangement, relative location of parts, steps and series of steps, all as hereinafter fully described.

In the accompanying drawings,

Figure 1 is a side elevational View of the spool end of a spooling machine, omitting the support for the deflecting pulley, diagrammatically illustrating the action of the subject matter of this invention.

Figure 2 is a front end elevational view of the structure of Figure 1, showing, however, the subject matter of this invention in full structural detail.

Figure 3 is a side elevational detailed view of the subject matter of the invention.

Figure 4 is a vertical central cross-sectional view through the damaged wire spool associated with the main spool.

After wire and the like has been processed as by coating, for example, it is wound on spools or wound into reels for handling and transportation. It is usually the case that the initial end of wire, due to threading of machine, has not been processed or is otherwise unusable and should be disposed of before or at the time the wire is final- 1y spooled or coiled for use as a finished product. In accordance with this invention the spooling or coiling machine is so constructed that the damanged end may be attached thereto and coiled or spooled onto an auxiliary spool after which, without stopping the machine, it is transferred to the main spool which is then filled. This leaves the damaged end exposed so that it may be cut off and thrown away. As a result of this all of the wire on the main spool is perfect having no'damaged ends. In addition, the wire may be cut at the time of severance of the damaged end in such a way as to leave exposed the then initial end of the wire in any desired length for welding or otherwise attaching to the termiwrench holes H) are nal end of another spool where successive spools of wire are being used in some further processing or manufacturing operation. Thus it is possible to provide an uninterrupted supply of wire for any subsequent operations.

Referring to the drawings, there is shown diagrammatically at l a portion of a spooling or coiling machine which has projecting therefrom a power driven mandril 2 upon which the main spool 3 is mounted. Also supported on the mandril 2 is the smaller damaged end or auxiliary spool 4. As shown in Figure 4, the spool 4 consists of a cylindrical smooth portion 5 having a flange 6 at one edge and a closure end Wall 1 at the other projecting radially a small distance to provide the smaller flange 8. The wall 1 is provided with a thickened hub 9 having a threaded aperture by means of which the auxiliary spool may be screwed onto the end of the mandril 2 to lock it in place and to likewise lock the main spool 3 to the mandril if no other locking means are provided. As indicated in Figure 2, spanner provided to aid in locking the auxiliary spool on the mandril and to aid in taking it off. As illustrated, the spool assembly is enclosed Within a suitable guard Ill. As in the case of all spooling and reeling machines as now used a distributor is provided for guiding the wire to the spool so as to lay it in uniform layers. A portion of such a distributor has been illustrated in the figures as including an arm H with a guide pulley rotatably mounted on the end of it. As indicated by the arrows in Figure 1, a support II is part of a mechanism not shown for causing the guide pulley l2 to move longitudinally with respect to the spool back and forth as the machine operates to lay the wire on in smooth layers on contiguous turns.

Mounted on the guard ID or on any other suitable support in proper position is a supporting plate I3 provided with a slot, as shown in Figure 3, through which a threaded'rod HI passes. This rod is provided with a pair of lock nuts so as to make it possible to anchor the threaded rod I 4 at the desired point longitudinally of the slot and of the mandril 2. The end of the threaded rod l4 pointing towards the spool assembly has secured thereto in any suitable manner, as by welding, a vertical standard or support 16 having a pair of spaced side arms upon which is journalled the vertical shaft H. The upper end of the shaft l I is provided with a handle l8 and a spring operated detent H! which operates with an index plate 20 secured to the top of the standard I 6 so that the handle l3 and shaft ll may be moved to either of two desired positions. Secured to the lower end of shaft I! is an angle shaped arm 2! upon which is journaled a deflecting or guide pulley 22.

The operation of this machine will now be described. In order to spool a length of wire a fresh empty main spool 3 is mounted on the mandril 2 and locked thereon by means of the auxiliary spool 4, orother suitable locking means, for instance, an expanding type arbor. The path of the wire is indicated by the broken line W. As is clear from Figure 1, the wire comes from the source of supply over the top of guide pulley l2, under the spool 33, over the deflecting pulley 22 and around the top of the'auxiliary spool '4. The terminal end is fastened in a hole or slot in the flange of the spool 4, as shown in the figures. The deflecting pulley is in the position shown so that it will guide the wire as it comes from under the spool 3, over the flange of the spool 3 and onto the auxiliary spool i. The machine is now set in operation which, for the structure as illustrated, would involve clockwise rotation of the spool assembly as viewed fromFigure 2. As soon as sufficient wire has been wound onto the auxiliary spool 4 so as to get past the damaged and unacceptable end of the wire, the operator flips handle it from'the position shown to a position which is 90 with respect to the position shown so as to cause the deflecting pulley 22 to rotate in a counterclockwise direction (Figure 1) through a 90 angle. As a result of this, the wire now begins to'wind on the main spool which operation is continued until the spool is full. The damaged end may then be cut off and the auxiliary spool removed. This frees the loaded main spool 3. The point of severance of the damaged end can be made close into the flange of spool 3 or a portion may be left projecting so that that end can be welded or otherwise attached to the terminal end of another spool where lengths of wire greater than that contained on one spool are required in any later manufacturing or processing operation. It will be apparent from Figure 3 that by the 90 swing of the angular support 2 I, the wire will be thrown ofi of the deflecting pulley 22 so that it is then free thereof and may wind directly onto the .spool 3.

From the above description, it will be apparent that the structure of this invention provides a very simple means for accomplishing the objects herein disclosed. It will be clear to those skilled in the art that the details of the structure embodied in the drawings for the purpose of illustrating this invention may be varied without departing from the scope of this invention. I do not, therefore, desire to be strictly limited to the disclosure as herein given but rather by the 7 claims attached hereto.

What is claimed is:

1. In a machine of the type described, the combination including a rotatable mandril, a main spool mounted on said mandril, an auxiliary spool secured on said mandril, a longitudinally reciprocable wire guide for laying the wire on said main spool in adjacent turns, a deflecting pulley positioned opposite the flange of said main spool adjacent said auxiliary spool and lying at an angle 'to the axis of the spools and means for rotatably supporting said deflecting pulley so as to guide a wire from one side of the adjacent flange of the main spool to the other side and for bodily shifting said guide pulley through an angle of to throw the wire therefrom after which it is wound on the main spool.

2. In a machine of the type described, the combination including a power driven mandril adapted to receive a main spool, an auxiliary spool secured to said mandril, means for guiding a wire to said main spool and means for guiding the wire from said main spool to said auxiliary spool when in one of two positions, said last means being shiftable to another position to drop the wire therefrom whereby it is wound on said main spool.

3. In a machine of the type described, the combination including a power driven mandril adapted to receive a main spool, an auxiliary spool secured to said mandril so as to lock said main spool thereon, a distributor for guiding :a wire onto said main spool, a deflecting pulley for guiding the wire from the main spool onto the auxiliary spool, and means for rotatably supporting and bodily shifting said deflecting pulley so as to drop the wire therefrom whereby it is wound on said main spool.
